A procedure used for finding the equation of a straight line that provides the best approximation for the relationship between the independent and dependent variables is the?
Least Squares method
What is STD logic in vhdl?
In VHDL, std_logic is a data type. It is assigned to input and / or output variables. It means that the variable is a standard logic type i. e. a logic bit which accepts or provides one bit data, either 1 or 0.
Which of the following best describes the purpose of the Data Mining Risk Assessment application?
A and B. Provides improved surveillance of the PCOLS program. Analyzes data, and categorizing and summarizing the relationship.
What is scalar data type?
Scalar data is the opposite of vector data, in that it provides a magnitude without a direction. For example, speed is a scalar quantity because it provides magnitude without a direction, whereas velocity is a vector quantity because it provides the magnitude that speed provides, but supplies us with direction.
Is SPSS used in qualitative data analysis only?
No, SPSS (Statistical Package for the Social Sciences) is not limited to qualitative data analysis only. In fact, SPSS is primarily designed for quantitative data analysis, which involves analyzing numerical data using statistical techniques. It is widely used in fields such as social sciences, psychology, economics, and market research. SPSS provides a range of features and tools for SPSS quantitative data analysis, including: Descriptive statistics: SPSS allows you to calculate and summarize descriptive statistics such as means, standard deviations, frequencies, and percentages. These statistics provide an overview of the distribution and characteristics of your data. Inferential statistics: SPSS offers a variety of statistical tests for making inferences about populations based on sample data. These tests include t-tests, ANOVA (Analysis of Variance), chi-square tests, correlation analysis, regression analysis, and more. Data manipulation: SPSS provides functionalities to manipulate and transform data. You can recode variables, compute new variables, merge datasets, filter cases, and perform various data transformations to prepare your data for analysis. Data visualization: SPSS enables you to create charts, graphs, and plots to visually represent your data. This helps in understanding patterns, relationships, and trends in the data. Advanced statistical techniques: In addition to basic statistical tests, SPSS also supports more advanced techniques. For example, it offers tools for factor analysis, cluster analysis, discriminant analysis, survival analysis, and nonparametric tests.
What is the meaning of correlation coefficient?
The correlation coefficient takes on values ranging between +1 and -1. The following points are the accepted guidelines for interpreting the correlation coefficient:0 indicates no linear relationship.+1 indicates a perfect positive linear relationship: as one variable increases in its values, the other variable also increases in its values via an exact linear rule.-1 indicates a perfect negative linear relationship: as one variable increases in its values, the other variable decreases in its values via an exact linear rule.Values between 0 and 0.3 (0 and -0.3) indicate a weak positive (negative) linear relationship via a shaky linear rule.Values between 0.3 and 0.7 (0.3 and -0.7) indicate a moderate positive (negative) linear relationship via a fuzzy-firm linear rule.Values between 0.7 and 1.0 (-0.7 and -1.0) indicate a strong positive (negative) linear relationship via a firm linear rule.The value of r squared is typically taken as "the percent of variation in one variable explained by the other variable," or "the percent of variation shared between the two variables."Linearity Assumption. The correlation coefficient requires that the underlying relationship between the two variables under consideration is linear. If the relationship is known to be linear, or the observed pattern between the two variables appears to be linear, then the correlation coefficient provides a reliable measure of the strength of the linear relationship. If the relationship is known to be nonlinear, or the observed pattern appears to be nonlinear, then the correlation coefficient is not useful, or at least questionable.
What is research methodology?
this method provides an explanation about the extent of relationship between two or more variables. it examines the relationships including similarities or differences among several variables.
What is comparative research methodology?
this method provides an explanation about the extent of relationship between two or more variables. it examines the relationships including similarities or differences among several variables.
Relationship of history and other discipline in social sciences?
Correlation is the innovation of the subjects and activities. It is a technique which tries to establish a reciprocal relationship among the various subjects of the curriculum. History provides a rich ground for correlation with different subjects as well as correlation with different places and times. Trevelyan has very aptly remarked, "History is not a subject at all but a house in which all subjects dwell."
Is Coefficient of correlation is independent of change of origin and but not scale?
No. It is independent of both. See the link. Notice in the definitions, for both the population and sample versions of the coefficient, that the numerator involves subtracting both means and the denominator provides for dividing by both standard deviations. This makes both coefficients location and scale invariant.

What is Functional relationship?

Why use of external variables is discouraged?
External variables, or global variables, are generally frowned upon because any code with access to the variables can alter the variables in unexpected ways. Object oriented programming addresses this problem by allowing programmers to encapsulate those variables into an object (often a singleton object) which provides far greater control over how those variables may be altered.
Bacteria have a mutualistic relationship that provides plants with what?
Nitrogen
What is the difference between a constant and a coefficient?
In a linear equation given as y = mx + c, the c represents a constant. This is because the x- and y- variables don't directly influence it, and it remains exactly what it is - constant - no matter what.The m is the coefficient - the value which provides scale. It also remains constant, but it is coupled to the variable of this equation, x.In the quadratic equation y = ax2+ bx + c, the 'c' here is a constant, and both 'a' and 'b' are coefficients.Both 'a' and 'b' are attached to the variable x, so both are considered coefficients. This rule holds true for all orders of polynomials.(Important note: The letter 'c' is not always used to represent the constant value in an equation, so watch out - so long as it isn't influenced by the variable of the equation, it's the constant.)
